Best solar panel angle in Ciampea
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
9°collects the most energy over a year: 1435 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Ciampea produces the most over a year at 9°. The design month for an off-grid system is February: at 0° it makes 3.52 kWh per kWp a day, 2% more than at 9°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Ciampea at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 9° (year-round best).

Sizing example. To run a 1 kWh-per-day load through January on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 910 Wp of panels at 70°, versus 340 Wp at 9°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
